Homepage Slider Aligned Left instead of Center.

[nicedayvince]

Please see http://socalelectricbikes.com and see that the homepage slider is pushed to the left. 

(I believe this may only happen on small monitors) I have a 13.2" macbook pro. 

How do I fix this?

Big screens have this issue too. Have a look:

Try to add the following rule to your CSS:

#slider_welcome {
    margin: 0 auto;
    max-width: 680px;
}

680px is the width taken from the child element of the slider block.

Thank you MagWorxTeam, How can I find the correct path to this CSS file? Thanks.

I have located the file path:

frontend/affinity/default/template/rokmagemodules/rokmage-contentslider/rokmage-content-slider.phtml

Now I need to know, on what line do I insert this snippet?
